What is re?Presumably, you have used a-character "*" when searching for files. For example, if you want to find all the Word files in the Windows directory, you may use "*. doc "is used for search, because" * "represents any character.

The main function of RE is to describe this specific style. Therefore, you can regard re as a descriptive s

Requirement: Give a group of numbers (N) and obtain the first K smallest numbers: The formal description is as follows: Number of groups: C1, C2 ,..., CN unordered arrangement a, set C1 Algorithm idea: Use the given number of first K to create the largest heap, and determine the number of next n-k one by one. AI (k If the AI is the largest in the heap, the maximum number in the heap is deleted and the AI is inserted. In this way, the first K minimum number in sequence a is the K number in the
